In some embodiments, user device 110 is implemented as a computing device including hardware and/or software modules configured to authenticate user 130, receive a request for content from user 130, retrieve external content data and/or supplemental external data from external data source 132, process the received external content data and/or supplemental external data to produce content, display content to user 130, and track and characterize the gaze and/or expression of user 130. In these embodiments, user 130 is an end-user of user device 110 that provides input to user device 110 in order to consume content. In an example, user 130 is an agent wishing to read reference information regarding one or more products offered by the company employing the agent.

In some embodiments, communication module 112 is implemented as a software module running on associated hardware, further detailed in FIG. 3, that is configured to receive command data from content processing module 128, process the received command data to produce query data, provide the query data to an external data source 132, receive result data from external data source 132, process the received result data into data, and provide the external content data to content processing module 128. In other embodiments, communication module 112 is further configured to process the received result data into external supplemental data and to provide the external supplemental data to content processing module 128. In some embodiments, communication module 112 sends and receives data via a wired or wireless connection using a desired protocol (e.g., TCP/IP, HTTP, UDP, IMAP, and the like).

In some embodiments, query data includes requests for external content data contained within command data. In an example, query data includes a request for one or more portions of text associated with a policy/contract, company guideline, and the like. In these embodiments, external content data includes text and/or media (e.g., RSVP text, images, audio, video, and the like), status messages (e.g., server down, information not found, a listing of potential matches, and the like), or the like. In other embodiments, query data includes requests for supplemental data specified within command data. In these embodiments, query data includes a request for a definition of one or more terms in text previously presented to user 130, a request for media associated with the one or more terms, and the like. In an example, query data includes a request for the term “beneficiary,” which has been previously presented to user 130 employing RSVP of the associated text.

RSVP content can be displayed on a user interface in a continuous manner, such that about 10 items (e.g., words, phrases, figures, images, pictures, sentences, phrases) are presented per second. Each item is presented in the same position on the screen. A first portion of the content can comprise an item or a set of items, whereby a set of items can comprise a phrase, a sentence, a description, or the like. After a first portion of the content is displayed, a second portion can be displayed. If the system detects that the user has a state of discontent, confusion, unhappiness, etc., the system can display supplemental content related to that portion of the content. If the system detects that the user is focusing for a period on an item or has been looking away, the system can display supplemental content related to that portion to present content that may be easier to understand or more interesting.

In other embodiments, input/output module 114 is implemented as a software module running on associated hardware, further detailed in FIG. 3, and configured to receive input data from user interface 116, to process the received input data into instruction data, and to provide the instruction data to content processing module 128. In these embodiments, input/output module 114 is further configured to receive output data from content processing module 128, process the received output data to generate content, and provide the generated content to user interface 116. In other embodiments, input/output module 114 is configured to receive input data from user interface 116, to process the received input data into credential data, and to provide the credential data to authentication module 126.

In some embodiments, instruction data includes one or more of requests for content, instructions associated with the requests for content, actions associated with content being displayed by user device 110, and the like. In an example, instruction data includes requests for a specified text (e.g., a section of a contract and the like), settings associated with the display of said text (e.g., words per minute to display in a RSVP text reader, and the like), and/or commands associated with the specified text (e.g., pausing the displayed text, resuming the displayed text, scrolling through the text, and the like). In other embodiments, instruction data includes credentials associated with user 130, such as a username and password, biometric credentials, and the like. In yet other embodiments, content includes one or more of text and/or media (e.g., RSVP text, paragraph text, images, video, audio, and the like) and/or instructions for presenting the text and/or media (e.g., layout, RSVP speed, and the like).

In some embodiments, user interface 116 is implemented as a software module running on associated hardware, further detailed in FIG. 3, and configured to receive input from user 130, processes the received input into input data, provides the input data to input/output module 114, receives content from input/output module 114, and displays content to user 130. In these embodiments, input data includes user requests to display a desired set of content, user instructions associated with the display of content (e.g., pausing, rewinding, or skipping forward in media), credentials for authorizing a session on user device 110, and the like.

In some embodiments, eye-tracking module 118 is implemented as a software module running on associated hardware, further detailed in FIG. 3, and configured to receive command data from content processing module 128, processes the command data into hardware operation data, and provides the hardware operation data to eye-tracking sensor module 120. In these embodiments, eye-tracking module 118 is further configured to receive ocular sensor data from eye-tracking sensor module 120, processes the ocular sensor data to generate ocular engagement data, and provides the ocular engagement data to content processing module 128. Further to these embodiments, ocular engagement data includes one or more metrics characterizing the level of engagement of user 130 with content being displayed via user interface 116. In an example, the ocular engagement data includes data describing whether or not the gaze of User 130 is directed toward the content displayed via user interface 116, a general level of interest in the content displayed via user interface 116 as determined by the eye movements of user 130, and the like. In these embodiments, hardware operation data includes instructions for hardware operation, such as instructions to activate eye-tracking sensors, to begin to track the gaze of User 130, to stop tracking the gaze of user 130, and the like.

In some embodiments, eye-tracking sensor module 120 is implemented as software configured to control associated hardware, further detailed in FIG. 3, and configured to receive hardware operation data from eye-tracking module 118, interact with user 130 in order to generate ocular sensor data, and provide the ocular sensor data to eye-tracking module 118. In these embodiments, ocular sensor data includes data describing the movement of the eyes of user 130. In an example, eye-tracking sensor module 120 is implemented as software configured to control camera hardware (e.g., a camera pair, not shown) included within user device 110 that is configured to determine the direction of the gaze of user 130. In this example, ocular sensor data includes the length of stare of user 130 on one or more regions of content being displayed via user interface 116, whether or not user 130 is looking at one or more portions of content being displayed via user interface 116, and the path of the gaze of user 130 as user 130 views content being displayed via user interface 116.

Eye tracking module 118 may utilize sensor or camera data to determine the gaze of a user. In one embodiment, a light (e.g., infrared) is reflected from the user's eye and a video camera or other sensor can receive the corneal reflection. The eye tracking module 118 analyzes the ocular sensor data to determine eye rotation from a change in the light reflection. A vector between a pupil center and the corneal reflections can be used to compute a gaze direction. Eye movement data may be based upon a saccade and/or a fixation, which may alternate. A fixation is generally maintaining a visual gaze on a single location, and it can be a point between any two saccades. A saccade is generally a simultaneous movement of both eyes between two phases of fixation in the same direction.

In one implementation, the eye tracking module can use a dark-pupil technique, whereby if the illumination source is offset from the optical path, then the pupil appears dark as the retroreflection from the retina is directed away from the camera. In another implementation, the eye tracking module can use a bright-pupil technique, whereby if the illumination is coaxial with the optical path, then the eye acts as a retroreflector as the light reflects off the retina creating a bright pupil effect.

In another embodiment, a camera or sensor can track eye image features (e.g., retinal blood vessels) and follow the features as the eye rotates. It is preferable that the eye tracking data is obtained in a manner that is non-invasive.

In yet another embodiment, a camera or sensor can identify a location of an iris or pupil based on the circular shape or by detection an edge. The movement of the iris or pupil can then be detected.

In some embodiments, expression processing module 122 is implemented as a software module running on associated hardware, further detailed in FIG. 3, and configured to receive command data from content processing module 128, process the command data into hardware operation data, and provide the hardware operation data to expression sensor module 124. In these embodiments, expression processing module 122 is further configured to receive expression sensor data from expression sensor module 124, process the expression sensor data to generate emotional state data, and provide the emotional state data to content processing module 128. The expression sensor data represents a micro-expression of the user, which can be a brief, involuntary facial expression that is shown on the user's face while the user is experiencing the emotion.

Further to these embodiments, emotional state data can be processed to generate data describing the emotional state of user 130. In an example, emotional state data describes whether or not user 130 is confused by content being displayed via user interface 116. In this example, the emotional state data can be generated by implementing methods similar to those described in Chiu Mei-Hung, et al. “The role of facial microexpression state (FMES) change in the process of conceptual conflict.” British Journal of Educational Technology 45.3 (2014): 471-486. In these embodiments, hardware operation data includes instructions for hardware operation, such as instructions to activate expression sensors, to begin to track the expression of user 130, to stop tracking the expression of user 130, and the like.

In some embodiments, expression sensor module 124 is implemented as software configured to control associated hardware, further detailed in FIG. 3, and configured to receive hardware operation data from expression processing module 122, interact with user 130 in order to generate expression sensor data, and provide the expression sensor data to expression processing module 122. In these embodiments, expression sensor data includes data describing micro-expressions of user 130 (e.g., expression skeletons describing facial states, and the like). In an example, expression sensor module 124 is implemented as software configured to control a camera, not shown, included within user device 110 that is configured to detect the micro-expressions of user 130. In this example, expression sensor data includes images of user 130 as user 130 views content displayed via user interface 116.

The expression processing module 122 can use a facial action coding system that recognizes changes in a facial expression and generates a score based on duration, intensity, and asymmetry. Facial expressions may have a duration of about 1/25 to 1/15 of a second, so the expression processing module 122 will receive a data feed of facial movements from a high speed camera having increments of less than one second to account for very quick changes. Some micro-expressions occur so quickly that a human observer cannot detect or sense the expression. In one embodiment, the expression processing module may require a threshold amount of time that a user holds a particular expression (e.g., 1/25 second, ¼ second, ⅓ second, ½ second) before adjusting content in view of that expression. In order to capture only micro-expressions, the expression processing module may also include a threshold of a maximum amount of time for that particular expression (e.g., ½ second, ⅔ second, ¾ second, 1 second, 1.5 seconds). In an alternative embodiment, the expression processing module is not limited to only micro-expressions.

In one example, the expression processing module may receive data from a camera or other sensor and process the data to determine that the user is in a state of disgust based on the expression sensor data. Data that may be relevant to determining the state of disgust can include data that represents that the user has raised an upper lid, raised a lower lip, wrinkled the nose, raised cheeks, and/or lines below the lower lid. In another example, a state of anger may be associated with a profile having data that represents lowered eyebrows, a wrinkled forehead, tensed eyelids, and tensed lips. A file containing a set of profiles, which may be stored in a database (not shown) associated with the server 240, may be used to match the expression sensor data by converting the data to generate action unit scores of the facial action coding system and then determining a similarity to any stored profiles.

Upon receiving this data, the expression processing module compares this data to stored profiles and can determine that this data matches a profile of disgust. Based on this determined profile, the system may generate additional content based on the content that was being viewed in association with this state. The additional content may be stored in a database and tagged with a particular state, such that if the user is disgusted with a price, additional content can be displayed that justifies the price or offers alternative pricing schemes.

In some embodiments, authentication module 126 is implemented as a software module running on associated hardware, further detailed in FIG. 3, and configured to receive credential data from input/output module 114 and processes the received credential data to determine whether user 130 is authorized to operate user device 110. In these embodiments, authentication module 126 may compare the received credential data to previously entered credential data, which is stored within a storage device within user device 110, associated with authorized use.

In some embodiments, content processing module 128 is implemented as a software module running on associated hardware, further detailed in FIG. 3, and configured to receive user instruction data from input/output module 114, receive ocular engagement data from eye-tracking module 118, receive emotional state data from expression processing module 122, process one or more of the received user instruction data, ocular engagement data, and/or emotional state data to generate command data, and to provide the command data to one or more of communication module 112, eye-tracking module 118, and/or expression processing module 122. In these embodiments, content processing module 128 is further configured to receive external content data from communication module 112, to retrieve internal content data from a storage device associated with user device 110 (further detailed in FIG. 3), and process said external content data and internal content data to generate output data. Further to these embodiments, content processing module 128 is configured to receive supplemental external data from communication module 112, to retrieve supplemental internal data from the storage device associated with user device 110, and process the supplemental external data and the supplemental internal data to generate output data.

In some embodiments, command data includes instructions for a communications module to retrieve data specified within user instruction data. In an example, command data includes instructions associated with communication module 112 for it to generate a desired query data. In this example, the instructions include request for specific content information. In these embodiments, command data includes instructions for eye-tracking module 118 and expression processing module 122 to begin operation. Further to these embodiments, internal content data includes text, images, and other media stored within a storage device associated with user device 110. In these embodiments, supplemental internal data includes text, images, and other media that is supplemental to content previously presented to user 130. Still further to these embodiments, output data includes text, images, video, and layout information. In an example, output data includes RSVP text to be presented to user 130.

In some embodiments, external data source 132 is implemented as a data source configured to receive query data from communication module 112, process the query data to generate result data, and provide the result data to communication module 112. In these embodiments, external data source 132 is implemented as a database that includes content information, such as for example images, text (e.g., books, articles, encyclopedia entries, blog posts, and the like), videos, metadata (e.g., relationships between images, texts, videos, and the like), and the like. In an example, external data source 132 is a database including company guidelines, sample policies, explanations of said policies, a glossary of terms associated with said policies, metadata about the relationship between the terms within the glossary of terms and one or more sample policies, and the like. In other embodiments, external data source 132 is implemented as a third party information source, such as an online encyclopedia, image server, video server, dictionary, and the like. In these embodiments, external data source 132 may be implemented as a database management system (DBMS), such as, for example, MySQL, PostgreSQL, SQLite, Microsoft SQL Server, Microsoft Access, Oracle, SAP, dBASE, FoxPro, IBM DB2, LibreOffice Base, FileMaker Pro and/or any other type of database that may organize collections of data, such as, for example, a relational database, a multi-dimensional database (MDB), and the like.

In operation, user 130 operates user device 110 via user interface 116. In some embodiments, user interface 116 receives a first input including credentials associated with user 130, processes the first input into first input data, and provides the first input data to input/output module 114. In these embodiments, input/output module 114 processes the first input data into credential data and provides the credential data to authentication module 126, and authentication module 126 verifies that user 130 is authorized to operate user device 110. Further to these embodiments, user 130 then operates user device 110 and provides a second input including a request that content (e.g., a specific RSVP text) be displayed on user device 110 via user interface 116. In these embodiments, user interface 116 receives the second input, generates second input data, and provides the second input data to input/output module 114. Still further to these embodiments, input/output module 114 generates user instruction data and provides the user instruction data to content processing module 128. In these embodiments, content processing module 128 processes the user instruction data and determines that one or more portions of the requested content are stored as internal content data within a storage device associated with user device 110, and further determines that one or more other portions not stored within said storage device may be stored as external content data within external data source 132. Still further to these embodiments, content processing module 128 generates a first command data including a request for external content data, and provides the first command data to communication module 112. In these embodiments, communication module 112 receives the first command data, generates a first query data, and provides the first query data to external data source 132. Yet further to these embodiments, external data source 132 receives the first query data, processes it to generate a first result data, and provides the first result data to communication module 112. In these embodiments, communication module 112 receives the first result data, processes the first result data to generate external content data, and provides the external content data to content processing module 128. Yet still further to these embodiment, content processing module 128 receives the external content data, retrieves the internal content data from the storage device associated with user device 110, and processes the external content data and internal content data to generate a first output data.

In some embodiments, content processing module 128 generates a second command data including instructions to begin operating eye-tracking sensor module 120 and provides the second command data to eye-tracking module 118. In these embodiments, eye-tracking module 118 receives the second command data, processes into a first hardware operation data, and provides the first hardware operation data to eye-tracking sensor module 120. Further to these embodiments, eye-tracking sensor module 120 begins to track the movements of the eyes of user 130 in order to generate ocular sensor data. In these embodiments, content processing module 128 additionally generates a third command data including instructions to begin operating expression sensor module 124, and provides the third command data to expression processing module 122. Still further to these embodiments, expression processing module 122 receives the third command data, processes it to generate a second hardware operation data, and provides the second hardware operation data to expression sensor module 124. In these embodiments, expression sensor module 124 begins to track the micro-expressions of user 130 in order to generate expression sensor data. Yet further to these embodiments, eye-tracking sensor module 120 and expression sensor module 124 track the gaze and expressions of user 130 as user interface 116 presents the content to user 130. In these embodiments, eye-tracking sensor module 120 then provides ocular sensor data to eye-tracking module 118, and expression sensor module 124 then provides expression sensor data to expression processing module 122. Yet still further to these embodiments, eye-tracking module 118 receives the ocular sensor data, processes it to generate ocular engagement data, and provides the ocular engagement data to content processing module 128. In these embodiments, expression processing module 122 receives the expression sensor data, processes it to generate emotional state data, and provides the emotional state data to content processing module 128. Further to these embodiments, content processing module 128 receives the ocular engagement data and the emotional state data and processes it to determine that user 130 requires supplemental content. In these embodiments, content processing module 128 then determines that one or more portions of the supplemental content are stored as supplemental internal data within a storage device associated with user device 110, and one or more other portions not stored within said storage device may be stored as supplemental external data within external data source 132. Still further these embodiments, content processing module 128 proceeds to generate a fourth command data including a request for supplemental external data, and provides the fourth command data to communication module 112.

In an example and referring to FIG. 2, communication network 608 is implemented to function in a manner substantially similar to first communications network 234.

FIG. 7 is a block diagram illustrating a first exemplary use case for presenting supplemental content to a user based on ocular and expressive feedback, according to an embodiment. In FIG. 7, use case 700 includes user device 702 and user 710. In FIG. 7, user device 702 includes rsvp text display 704 and supplemental content display 706. in some embodiments, the gaze of user 710 can be characterized by first gaze line 712 and second gaze line 714. Use case 700 can include additional, fewer, or differently arranged components than those illustrated in FIG. 7.

In some embodiments, user device 702 is implemented as a computing device configured to: receive a request for content from user 710; generate content from internal and/or external content data, display said content to user 710; generate ocular engagement data and emotional state data based on the behavior of user 710 as the content is being displayed; determine if supplemental content is needed based on the ocular engagement data and emotional state data; and generate supplemental content based on external and/or internal supplementary data. In an example and referring to FIGS. 1 and 3, user device 702 is configured in a manner substantially similar to user device 110 and user device 310. In these embodiments, RSVP text display 704 is implemented as a first portion of a user interface associated with user device 702 and configured to display RSVP text requested by user 710. Further to these embodiments, supplemental content display 706 is implemented as a second portion of a user interface associated with user device 702 and is configured to display supplemental content associated with content being displayed by RSVP text display 704.

In operation, user 710 requests a desired RSVP text be displayed on user device 702. In some embodiments, user device 702 retrieves internal content data from a storage device (not shown) and external content data from an external data source (not shown), generates the desired content, and displays the desired content (e.g., the desired RSVP text) on RSVP text display 704. In these embodiments, user 710 consumes the content, and the gaze of user 710 is characterized by first gaze line 712.

Further to these embodiments, user device 702 monitors the behavior of user 710 in order to generate ocular engagement data and/or emotional state data. In an example and referring to FIGS. 1 and 3, eye-tracking sensor module 120 controls eye-tracking sensor 326 and begins to track the movements of the eyes of user 130 in order to generate ocular sensor data, and provides the generated sensor data to eye-tracking module 118. In this example, Expression Sensor Module 124 controls Expression Sensor 328 and begins to track the micro-expressions of User 130 in order to generate expression sensor data, and provides the expression sensor data to Expression Processing Module 122. Further to this example, eye-tracking module 118 processes the ocular sensor data into ocular engagement data, and Expression Processing Module processes the expression sensor data into emotional state data.

The ocular engagement data can be assigned a value, which can represent an amount of time that the user's gaze is directed toward an item or away from the user interface. For example, if the user is gazing an item for more than one second, the user may not understand the item. In another example, if the user is gazing away from the user interface for more than one second, the user may be bored or distracted. In the exemplary embodiment, this threshold value is set at one second, but any time period can be used. When the value is above this threshold value, the system can query for supplemental content that is related to the content being displayed when the user was gazing for a long period of time or gazing away. A fixation for reading text may be about 200 ms in duration, so a threshold value can be based upon this value, whereby a threshold can be established at about 500 ms, 1 second, or 2 seconds. When detecting whether a user's eyes are distracted away from the displayed content, a different threshold value can be used, which can be established at 1 second, 2 seconds, 3 seconds, or 4 seconds.

The content processing module can assign a state of the user based upon the state data. The state data is associated with the content that was being displayed when the expression sensor data was captured. The expression sensor data is analyzed to determine whether any micro-expressions are associated with a particular state, such as disgust, anger, fear, sadness, happiness, surprise, amusement, contempt, embarrassment, anxiety, guilt, pride, relief, contentment, pleasure, shame, confused, distracted, upset, or content. If the state is content, then the content processing module will continue to present the next portion of RSVP content. If the user is associated with another state, the content processing module will query for supplemental content to display to the user, where the supplemental content is associated with the content that was associated with the determined state.

In some embodiments, user device 702 may then detect that user 710 looks away from rsvp text display 704 and towards supplemental content display 706, as characterized by second gaze line 714. In these embodiments, the generated ocular engagement data is used by user device 702 to determine that the user wishes to view information supplemental to the text being displayed on RSVP text display 704.

In some embodiments, user device 702 proceeds to pause the display of content on RSVP text display 704, generate supplemental content, and display the supplemental content on supplemental content display 706. In these embodiments, as user 710 views content on rsvp text display 704, user device 702 may analyze the generated emotional state data and detect that user 710 is feeling confused. Further to these embodiments, user device 702 may then proceed to pause the display of content on rsvp text display 704, generate supplemental content, and display the supplemental content on supplemental content display 706.

In an example, user 710 is an agent and requests information regarding a type of policy/contract. In this example, the information is stored as RSVP text and is displayed to user 710 via RSVP text display 704. As user 710 consumes the content, user device 702 observes user 710 and determines that user 710 is confused by the term “Beneficiary” being displayed on RSVP text display 704. In this example, user device 702 then pauses the content being displayed via RSVP text display 704 and generates supplemental content for display on supplemental content display 706. Further to this example, the supplemental content includes a definition for the term, the context of the term within the text, and/or statistics associated with the term (e.g., number of hits within the document, prevalence across multiple documents, and the like).

FIG. 8 is a block diagram illustrating a second exemplary use case for presenting supplemental content to a user based on ocular and expressive feedback, according to another embodiment. In FIG. 8, use case 800 includes user device 802 and user 810. In FIG. 8, user device 802 includes media display 804 and supplemental content pop-up 806. In FIG. 8, the gaze of user 810 can be characterized by fixed gaze line 812. In other embodiments, use case 800 can include additional, fewer, or differently arranged components than those illustrated in FIG. 8.

In some embodiments, user device 802 is implemented as a computing device configured to receive a request for content from user 810, generate content from internal and/or external content data, to display said content to user 810, generate ocular engagement data and emotional state data based on the behavior of user 810 as the content is being displayed, to determine if supplemental content is needed based on the ocular engagement data and emotional state data, and to generate supplemental content based on external and/or internal supplementary data. In an example and referring to FIGS. 1 and 3, user device 802 is implemented to function in a manner substantially similar to user device 110 and user device 310. In other embodiments, media display 804 is implemented as a first portion of a user interface associated with user device 802 and configured to display text and media requested by user 710. In yet other embodiments, supplemental content pop-up 806 is implemented as a second portion of a user interface associated with user device 802 and configured to display supplemental content associated with content being displayed by media display 804.

In operation, user 810 requests a desired content (e.g., RSVP text) be displayed on user device 802. User device 802 proceeds to retrieve internal content data from a storage device (not shown) and external content data from an external data source (not shown), generates the desired content, and displays the desired content on media display 804. User 810 proceeds to consume the content, and the gaze of user 810 is characterized by fixed gaze line 812. User device 802 then monitors the behavior of user 810 in order to generate ocular engagement data and/or emotional state data. In an example and referring to FIGS. 1 and 3, eye-tracking sensor module 120 controls eye-tracking sensor 326 and begins to track the movements of the eyes of user 130 in order to generate ocular sensor data, and provides the generated sensor data to eye-tracking module 118. In this example, expression sensor module 124 controls expression sensor 328 and begins to track the micro-expressions of user 130 in order to generate expression sensor data, and provides the expression sensor data to expression processing module 122. Further to this example, eye-tracking module 118 processes the ocular sensor data into ocular engagement data, and expression processing module processes the expression sensor data into emotional state data.

In some embodiments, user device 802 may then detect that user 810 looks fixedly at a particular area displayed on media display 804, as characterized by fixed gaze line 812. In these embodiments, the generated ocular engagement data is used by user device 802 to determine that the user wishes to view information supplemental to the text being displayed on media display 804. User device 802 proceeds to generate supplemental content and to display the supplemental content on supplemental content pop-up 806.

FIG. 9 is a block diagram illustrating a third exemplary use case for presenting supplemental content to a user based on ocular and expressive feedback, according to another embodiment. In FIG. 9, use case 900 includes user device 902 and user 910. In FIG. 9, user device 902 includes user interface 904, drop-down menu 906, and selection 908. In FIG. 9, user 910 displays first gaze line 912 and second gaze line 914. In other embodiments, use case 900 can include additional, fewer, or differently arranged components than those illustrated in FIG. 9.

In some embodiments, user device 902 is implemented as a computing device able to receive a request for content from user 910, generate content from internal and/or external content data, to display said content to user 910, generate ocular engagement data and emotional state data based on the behavior of user 910 as the content is being displayed, and to perform actions based on the ocular engagement data and emotional state data. In an example and referring to FIGS. 1 and 3, user device 902 is implemented to function in a manner substantially similar to user device 110 and user device 310. In another example and referring to FIGS. 1 and 3, user interface 904 is implemented to function in a manner substantially similar to user interface 116 and user interface 318 and configured to display drop-down menu 906 and selection 908.

In operation, user 910 requests a desired content (e.g., a form) be displayed on user device 902. User device 902 proceeds to retrieve internal content data from a storage device (not shown) and external content data from an external data source (not shown), generates the desired content (e.g., a form), and displays the desired content on user interface 904. User 910 proceeds to consume the content, and the gaze of user 910 is monitored in order to generate ocular engagement data and/or emotional state data. In an example and referring to FIGS. 1 and 3, eye-tracking sensor module 120 controls eye-tracking sensor 326 and begins to track the movements of the eyes of user 130 in order to generate ocular sensor data, and provides the generated sensor data to eye-tracking module 118. In this example, expression sensor module 124 controls expression sensor 328 and begins to track the micro-expressions of user 130 in order to generate expression sensor data, and provides the expression sensor data to expression processing module 122. Further to this example, eye-tracking module 118 processes the ocular sensor data into ocular engagement data, and expression processing module processes the expression sensor data into emotional state data.

In this exemplary embodiment, a user is viewing a display presenting a form. As the user completes the form by entering inputs into a computing device, the system can sense micro-expressions and/or eye tracking to determine where the user may be having difficulty with the form or to get other feedback on portions of the form. If, for example, the user is sensed to have difficulty answering or completing a particular portion of a form, the system can present additional content in the form of a new window that is generated and displayed over the display of the form. The new window can include information about the particular portion of the form content that is causing difficulty for the user. If the user appears distracted, the system can present questions to prompt the user rather than passively wait for the responses to be inputted.

In some embodiments, user device 902 may then detect that user 910 looks fixedly at a particular area displayed on user interface 904, as characterized by first gaze line 912 and proceeds to select and activate drop-down menu 906. In these embodiments, the generated ocular engagement data is used by user device 902 to determine that the user wishes to select an option on drop-down menu 906, and proceeds to activate selection 908.

FIG. 10 is a flow chart of an exemplary method for presenting supplemental content to a user based on ocular and expressive feedback, according to an embodiment. In some embodiments, said method may be executed in system hardware and software architectures similar to those described in FIGS. 1-9, above.

In FIG. 10, process 1000 begins at step 1002. At step 1002, a user powers a user device on. In an example and referring to FIGS. 1 and 3, user 130 powers on user device 110. In an example, user device 110 is powered on when user 130 inputs a command via an input/output device. In some embodiments, the user device loads a content processing module, an authentication module, a communication module, an input/output module, an eye-tracking module, and an expression tracking module from the user device memory into the user device processor, which instructs the device processor to execute the method described herein. Process 1000 proceeds to step 1004.

At step 1004, the authorization module is loaded into memory by the processor and instructs the processor to execute instructions to: receive credential data; compare the received credential data to credentials previously stored within the storage device; and determine if the user is authorized. If the user is authorized to operate the user device, process 1000 continues to step 1006. Otherwise, process 1000 ends.

At step 1006, the input/output module is loaded into memory by the processor and instructs the processor to execute instructions to receive input from the user including a request that a specified content is presented. At this step, the input/output module instructs the user device processor to process the input to generate user instruction data, and provides the user instruction data to the content processing module. The content processing module then instructs the processor to process the user instruction data, and determines if the request requires the retrieval of external content data and/or internal content data. The content processing module then generates the command data required to carry out the instructions within the user instruction data. Process 1000 proceeds to step 1008.

At step 1008, the content processing module is loaded into memory by the processor and instructs the processor to execute instructions to provide command data to the communications module to retrieve external content data and/or supplemental external data from the external data source. The communications module then instructs the user device processor to provide query data to the external data source via the user device interface. The external data source receives the query data, processes it, and returns result data to the communications module. The communications module then carries out instructions on the user device processor in order to process the result data and provide the external content data and/or supplemental external data to the communications module. The communications module then carries out instructions on the user device processor to retrieve internal content data and/or supplemental internal data from the storage device associated with the user device. Process 1000 then proceeds to step 1010 and step 1014.

At step 1010, the content processing module is loaded into memory by the processor and instructs the processor to execute instructions to instruct the user device processor to process the internal content data, external content data, supplemental internal data, and/or supplemental external data to generate output data. The content processing module then provides the output data to the input/output module, and the input/output module carries out instructions on the user device processor to process the output data into content, and the input/output module displays the content on an input/output device (e.g., a display). In some embodiments, the user interface associated with the user device includes one or more regions where a specified content is to be displayed. Process 1000 proceeds to step 1012.

At step 1012, the content processing module is loaded into memory by the processor and instructs the processor to execute instructions to: determines if the user wishes to continue viewing content. In some embodiments, the content processing module determines that the user wishes to continue viewing after processing user instruction data provided by the input/output module. If the user wishes to continue viewing data, process 1000 proceeds to step 1008. Otherwise, process 1000 ends.

At step 1014, the content processing module is loaded into memory by the processor and instructs the processor to execute instructions to send command data to the eye-tracking module and the expression processing module, including instructions to activate the eye-tracking sensor and the expression sensor. At this step, the processor carries out instructions to prepare the user device to track the gaze and microexpressions of the user, such as for example by allocating the memory and other system resources needed to track the gaze and microexpressions of the user. Process 1000 continues to step 1016.

At step 1016, the eye-tracking module and the expression processing module are loaded into memory by the processor and instruct the processor to execute instructions to track the gaze and the microexpressions of the user. At this step, the eye-tracking module uses ocular sensor data from the eye-tracking sensor (e.g., images, gaze path curves, and the like) to determine the level of ocular engagement the user has with the content being displayed by the user device. The eye-tracking module then provides the ocular engagement data to the content processing module. Further at this step, the expression processing module uses expression sensor data from the expression sensor (e.g., images and the like) to determine the emotional state of the user (e.g., confusion). The expression processing module then provides the emotional state data to the content processing module. Process 1000 continues to step 1018.

At step 1018, the content processing module is loaded into memory by the processor and instructs the processor to execute instructions to process the ocular engagement data and the emotional state data to determine if supplemental content is required. At this step, the content processing module determines if the ocular engagement data of the user indicates that the user is focusing his or her gaze on the content, or whether they have looked away or shown some other indicator of disengagement from the content. If the content processing module determines the user has disengaged with the content, the content processing module may pause the display of content on the user device and generate command data to retrieve supplemental data associated with the content being displayed on the user device. Further at this step, the content processing module determines if the emotional state data of the user indicates that the user is confused by the content being displayed on the user device. If the content processing module determines that the user is confused by the content, the content processing module may pause the display of content on the user device and generate command data to retrieve supplemental data associated with the content being displayed on the user device. If the command processing module determines that supplemental content is required, process 1000 proceeds to step 1008. Otherwise, process 1000 proceeds to step 1016.
